Assessment: Apache-2.0 platform and MCP server, run with `uvx mcp-server-datahub@latest` or the acryldata/mcp-server-datahub Docker image against DataHub Core or DataHub Cloud. The eight default tools carry about 26,000 characters of descriptions, and search and get_lineage each repeat the same 3,063-character filter grammar.

## Facts

- Kind: Model platform · vendor: Acryl Data, Inc. (DataHub) · category: Company knowledge & data catalogues · legal entity: Acryl Data, Inc. (d/b/a DataHub) · provenance 75/100
- Endpoint: `https://mcp.datahub.com/mcp` (stdio, HTTP, Streamable HTTP)
- Auth: OAuth or key · pricing: Freemium · x402: no · licence: Apache-2.0 (DataHub Core and mcp-server-datahub). DataHub Cloud, its managed MCP endpoint and Cloud-only tools such as find_sql_context are closed
- Probe metrics: not measured yet (probes haven't run)
- Self-hosting: DataHub Core is Apache-2.0 and free. The MCP server needs Python 3.11+ and runs by `uvx mcp-server-datahub@latest` over stdio, or as the acryldata/mcp-server-datahub image over HTTP on port 8000
- MCP server: mcp-server-datahub 0.7.1 (16 September 2026). 8 read tools by default (the 2 document tools hide when no documents exist), 12 write tools behind `TOOLS_IS_MUTATION_ENABLED`, `get_me` behind `TOOLS_IS_USER_ENABLED`, `get_dataset_assertions` behind `DATA_QUALITY_TOOLS_ENABLED`. 22 in all
- Managed MCP: DataHub Cloud only, at https://mcp.datahub.com/mcp or https://<tenant>.acryl.io/mcp. OAuth with dynamic client registration from Cloud v1.0.2, bearer tokens otherwise. The docs list Cloud-only tools such as find_sql_context, draft_sql_for_tables and glossary proposals
- Credentials: Personal access tokens per user with 1-hour to 365-day expiry, never-expiring off by default. HTTP mode takes per-user bearer tokens in the header only. No per-token scopes
- Context controls: `num_results` capped at 50 with `offset`, facet-only search with `num_results=0`, `TOOL_RESPONSE_TOKEN_LIMIT` default 80,000, DataHub views to narrow what search sees
- Telemetry: On by default to Mixpanel through track.datahubproject.io. `DATAHUB_TELEMETRY_ENABLED=false` turns it off, and it switches itself off in CI. The MCP server adds a per-call event with tool, client and error text
- APIs: GraphQL, an OpenAPI spec served by each instance at /openapi/v3/api-docs, and Rest.li. Python SDK acryl-datahub
- Releases in 90 days: DataHub v1.7.0 (4 August), v1.6.0.1, v1.6.0.2, v1.7.0.1 and v1.6.0.3 (25 September, LTS hotfix). MCP server 0.7.0 and 0.7.1
- DataHub Cloud: Contact sales. 99.5 per cent uptime SLA and SOC 2 per the Cloud vs Core page. Status page status.datahub.com on incident.io

DataHub Cloud and its extra MCP tools are closed (27 of 30).

## Before you call it

1. Start keyword queries with `/q` and pass filters as one string, such as `entity_type = dataset AND platform = snowflake`
2. Call `search` with `num_results=0` first to get the tags, glossary terms, platforms and domains in use
3. Page with `offset`. `num_results` is capped at 50
4. Expect no write tools unless the operator set `TOOLS_IS_MUTATION_ENABLED=true`, and create tags and terms before `add_tags` or `add_terms` refers to them
5. Use https://mcp.datahub.com/mcp with OAuth only on DataHub Cloud v1.0.2 or later. DataHub Core needs the local server and a personal access token

## Connect

```bash
uvx mcp-server-datahub@latest
```

```bash
claude mcp add datahub \
  -e DATAHUB_GMS_URL="<your-datahub-url>" \
  -e DATAHUB_GMS_TOKEN="<your-datahub-token>" \
  -- uvx mcp-server-datahub@latest
```
